I don't understand the failure. It looks completely unrelated to this PR but it happened only on an Apple builder.

The linker cc exited with signal 4 (SIGILL, so presumably an abort) when trying to compile this doctest.

@sfackler I can't reproduce this locally (after a rebase so I should be testing the same thing as bors). I think it's probably spurious. Could you re r+?.
